Skate 3 Share Pack Not Available on Latin American PlayStation Store

Hi - I wanted to ask why the Skate 3 Share Pack is not available on LATAM PS3 Store. I have a Latin American account, and I'm using the game disc BLUS30464. Trying to search for "Skate 3" on the PS3 Store brings nothing, not even a single DLC, when it should be there. I need the DLC so I can obtain the trophy related "Artsy Fartsy". While is technically free, is not available on Latin American countries PS Store. I also own a American PSN account, but unfortunately the DLC is not there too. If the DLC was delisted, it's a shame. I love Skate 3, but if this pack is not available, then I guess I'll pass on getting the platinum trophy.
